Magnetic Fluid Level Sensor
The magnetic fluid level sensor (Figure 13-7) monitors the fluid level inside a syringe. It connects to a
special power cord labeled
Fluid Level Sensor on the dispense head. The sensor is held by a bracket that
attaches directly to the fluid cartridge. This fluid level sensor is available for 74 cc (2.5 fl oz) cartridges
only.
Item Description
1 Fluid Level Sensor
Figure 13-6 Magnetic Fluid Level Sensor
This sensor detects a magnet on top of the follower inside of the fluid cartridge. The sensor is mounted
near the bottom of the fluid cartridge. When the fluid level gets low enough, the sensor detects the magnet
on top of the follower, resulting in a low fluid warning.
Operation is automatic. The only operator intervention required is when a low fluid alarm dialog box is
issued from FmNT. The operator is given three options after a low fluid warning has been issued and the
pre-set number of remaining boards has been completed:
• Ignore the warning and continue dispensing.
• Add an additional number of boards to be dispensed and then continue.
• Stop the run and change the syringe.
Experimenting with these options can maximize your fluid use.
